Precision spring options for Mini-Z AWD tuning

This spring set is produced for Kyosho Mini-Z AWD MR-03 suspension tuning and is identified by part MZA0345SP. It contains three pairs of coil springs in 0.3mm, 0.4mm and 0.5mm wire diameters, each with a consistent 5.2mm free length to aid repeatable rate comparisons during setup and testing.

Designed to provide predictable changes in suspension stiffness, the different wire diameters let you refine front to rear balance without altering static ride height. During installation verify correct seating on the shock retainer and match left and right orientations to maintain symmetric behaviour.

For methodical tuning, change one axle or corner at a time and record the effect of each spring swap. These components are intended as aftermarket tuning parts for model-scale suspension systems and support consistent, repeatable setup work.

How are spring rate differences best evaluated?

Conduct controlled runs swapping only one pair at a time, record lap times and handling notes, and compare changes to a defined baseline setup.

What should I check after fitting a new spring?

Confirm spring seating, correct preload on the retainer and symmetry across the chassis to avoid directional bias.

Can I mix these with different shock oils or pistons?

Yes, spring rate is one variable; combine with suitable shock oil and pistons to tune damping and achieve the desired dynamic response.
